Schneider 140NRP95401C Coated Fibre Optic Repeater for Modicon Quantum

Product Introduction

When signal degradation threatens communication in harsh industrial environments, the Schneider 140NRP95401C provides a reliable solution. This coated fibre optic repeater, part of the Modicon Quantum automation platform, extends and stabilizes data transmission over long distances using single-mode fiber. Designed for demanding applications, it ensures minimal signal loss and robust performance.

Technical Specifications Breakdown

The 140NRP95401C operates with a bus current requirement of 750 mA and power dissipation of 5 W, ensuring efficient energy use. Its inrush current reaches 1.8 A at 5 V DC, enabling reliable startup. The device features two fiber optic ports with LC connectors and one coaxial connector port, offering flexible networking options. It supports single-mode fiber with a receiver sensitivity of -25 dBm and can detect silence down to -45 dBm, allowing precise signal monitoring. The rise/fall time of 20 nanoseconds supports high-speed data transmission.

Industry Applications

In manufacturing plants, the 140NRP95401C links remote control cabinets to central PLCs, overcoming electrical noise and distance limitations. For oil and gas facilities, it provides reliable communication between distributed I/O modules and the main controller in explosive or corrosive environments. Its operating temperature range of 0 to 60°C and humidity tolerance of 0 to 95% (non-condensing) make it suitable for both indoor and sheltered outdoor installations.

Installation & Setup Guidance

Mount the 140NRP95401C on a DIN rail within the Modicon Quantum rack. Connect single-mode fiber cables to the LC ports and coaxial cable to the coaxial connector. Ensure the bus current supply meets the 750 mA requirement. The device provides local signaling via four green and three red LED indicators for quick status checks. Operate below 2,000 meters altitude to maintain performance.

Maintenance & Reliability

Regularly inspect the fiber optic connectors for dust or damage to maintain signal integrity. The polycarbonate housing resists impact and corrosion. Store the unit between -40 and 85°C when not in use. The 140NRP95401C's low power dissipation and robust design reduce downtime and extend service life, offering long-term value for critical automation networks.
